LVVEATOR THOMAS J. MURRAY,'.OF SPRINGFIELD, MASSACHUSETTS.

FLUSHING APPARATUS FOR WATER-CLOSET BOWLS.

Specification of Letters Patent.

Application filed January 5, 1909. Serial No. 470,889.

To all whom it may concern:

Be it known that I, THOMAS J MURRAY,

a citizen of the United States of America,

and resident of Springfield, in'the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Flushing Apparatuses for VVater- Closet Bowls, of which the following is a' full, clear, and exact description.

This invention relates to flushing devices for water-closets and more particularly to b that class thereof in which water accumulates in a tank under pressure and is permitted to flow into the bowl upon the release action of a valve, andit has for one of its objects the provision of such a device in which the release valve is controlled by a device which is adapted to be operated by hand and which permits water under pressure to act directly upon said valve.

My invention has, furthermore, for its object the combination with a receiver, of a drain-chamber into which the water from the receiver will pass as permitted by a valve mechanism interposed between these two elements.

My invention has also for its object the improved construction and organization of some of the component elements as will be hereinafter described, and the means of attainment of which will be particularly pointed out in the claims.

The invention has been clearly illustrated in the accompanying drawings in which similar characters denote similar parts, and in which-- Figure 1 re resents a longitudinal centtral section of a ushingdevice embodying my invention, and Fig. 2 is asimilar view illustrating the parts in their flushing or active positions.

Briefly stated, the present device .comprises a receiver-tank connected directly with the water supply under pressure, and having at. its upper portion. a float valve which is closedby the rise of the water with:

'in the same. Disposed in conjunction with this receiver-tank is a drain-chamber which is connected directly with the bowl of a water-closet, and into which the water from the receivertank enters after passing a valve, the opening action of which is effected by water pressure admitted by a manually operated controller, while at the same time b means are provided whereby the valve .actuatmg pressure water will find a gradual exit into the drain-pipe in such a manner as to permit the valve to close slowly-so that the action of the valve closing will be retarded as desired.

Referring to the drawings, the numeral 10 denotes a receiver-casing preferably pro-' vided with a splash-wall 11 and connected with a suitable water supply under pressure by means of a pipe 12 which may have a pressure regulating valve 13 of ordinary construction.

Disposed in the bottom of the receivertank 10 is a valve-seat 14 adapted to receive a valve 15 which is secured upon a stem 16 guided for vertical movement in a bearing 17 attached to, or constituting a part of the receiver-casing 10. The lower end of the valve-stem 16 carries a piston 18 preferably of the cup-leather type which is movable in a pressure cylinder 19 connected by a pipe Patented Aug. a1, 1909.

20' with the controlling device indicated herein in a general way by C, and connected with the main water supply by a pipe 21. The controlling device comprises a valve 22 secured to a longitudinally movable stem 23 and operable by a hand lever 24 whereby said valve may be pushed from its seat to permit water under pressure to pass from the pipe 21 into the pipe 20. The valve 22 with a stem 23 are of the self closing type, but, if desired, a spring or weight may be employed to accomplish that purpose.

,to a drain-chamber 29 adapted to receive the watei' passing the valve 15, and standing in constant open communication with the bowl of the water-closet, as for instance, by a pipe 30 held in place thereon by a flange 31. Hence it will be seen that any leakage of water through the opening 27 will be C0ll.- ducted into the drain chamber 29, andbe from thence allowed to escape through the pipe 30 to the bowl. It will, therefore, also I 55 3 supply pipe 12 is in constant and open communication with the tank.

be understood that the water entering the drain-chamber 29 directly from the receivertank by passing the valve will also be drained in a like manner, this body of water constituting the flush for the bowl.

The pressure cylinder 19 may be supported Within the drain-chamber 29, as for instance, by a bracket 32, and it is' provided with a vent 33 at its bottom to permit the waterin said cylinder, after it has performed its function in raising the valve 15, to gradually escape and thus permit the valve'15 to close in as slow a-manner as controlled by the size of the opening 33. i

The operation of my improved flushing device can be readily ascertained by a comparison of Figs. 1 and 20f the drawings,

Jig-1 representing the parts in their posivalve 15 has been raise a water in the tank 1O will immediately flow tion ready to'operate while in Fig. 2 the hand lever 24 is manually operated to open the control-valve to establish a flushing action during which the parts assume positions as here shown. Referring to Fig. 1 it will be seen that the receiver-tank 10 is completely filled with water under pressure in troduced thereinto through pipes 12 and 12, the valve 25 at its top being closed by virtue of the water pressure within said tank. When now pressure is exerted upon the handle 24 to open the control valve 22, as shown in Fig. 2, water under pressure is permitted to pass through the pipe 21, past the valve 22 and through the pipe 20 into the pressure cylinder 19 which it will fill, and where it will serve to force the valve 15 upward and from its seat by virtue of the area of the piston 18 being greater than that of the valve 15. The pressure on the otherside of the piston is (in the position shown in Fig. 1,) ml because the drain-chamber is connect'ed by the passage 28 with the open air, as at 28, at a point sufiieiently high to prevent the water in seeking its level in the receiver 10 from splashin out. As'soon as from its seat, the

into the drain-chamber 29 in greater volume than fresh water will be supplied to said tank through the pipe 12', and the water received by the dram-chamber can find a free and unobstructed passage through the drain I pipe 31'connected with the bowl of the closet,

so. that ,in this mannenwater will at first .be preglpltated from the receiver tank into the dram-chamber inasmuch as the water It should be noted that the drain-pipe 30 is considerably larger in area than the inlet fipipe 12, so

trol valve 22 has been allowed to close, the

water in the pressure cylinder 19 will slowly escape through the aperture 33 above mentioned, and the closing action of the valve 15 will, therefore, be retarded. Any water contained within the pressure cylinder 19, after the valve 15 has come to its closed position, will be drained from said cylinder and the pipe 20 through the aperture 33, so that these portions of the device will also be free from water while any leak which may exist in the control-valve22 cannot work any injury to the devicefas will be readily understood. After the valve 15 has come to its closed position fresh water entering the tank 10 will gradually fill the same and drive the air before it through the aperture 27 until the water in its rising movement in the tank will come in contact with the ball-valve 25 and close the aperture 27, as indicated in Fig. 1 whereupon the flushing device is again ready for use.- i
